VizieR Online Data Catalog: Masses and ages of 1059 HARPS-GTO stars (Delgado Mena+, 2019)
Abstract
The baseline sample used in this work consist of 1111 FGK stars observed within the context of the HARPS-GTO planet search programs (Mayor et al., 2003Msngr.114...20M; Lo Curto et al., 2010, Cat. J/A+A/512/A48; Santos et al., 2011, Cat. J/A+A/526/A112). The final spectra have a resolution of R~115000 and high signal-to-noise ratio (45% of the spectra have 100<S/N<300, 40% of the spectra have S/N>300 and the mean S/N is 380). Precise stellar parameters for the full sample of 1111 stars within the HARPS-GTO program were homogeneously derived in Sousa et al. (2008, Cat. J/A+A/487/373, 2011a, Cat.J/A+A/526/A99, 2011b, Cat. J/A+A/533/A141). The parameters for cool stars were revised by Tsantaki et al. (2013, Cat. J/A+A/555/A150) using a special list of iron lines which was later applied to the full sample in Delgado Mena et al. (2017, Cat. J/A+A/606/A94), also correcting the spectroscopic gravities. From the 1111 stars in the original sample, the derivation of parameters converged to a solution for 1059 of them.
